Stable Total Ossicular Replacement Prosthesis Design • • • 1 Total Ossicular Replacement Prosthesis (TORP) – Used to restore hearing when the bones of hearing (incus, malleus and stapes) are broken or absent – Placed onto the stapes footplate and attached to the eardrum to transmit the mechanical energy of a vibrating ear drum to the cochlea – Current TORP models are difficult to implant, hard to keep in place, and do not fully restore hearing Group Size: 2 -3 Students would work to create novel reconstruction prosthesis designs, and work to create phantom models to validate the success of their designs. Skills: 3 D Modeling, Force Sensors, Materials Design Mentors: Pete Creighton, MD / Chris Razavi, MD / John Carey, MD – Francis.

Middle Ear Surgery Phantom • Surgery of the middle ear to restore hearing is very delicate and complex, and no models exist to test surgeon skill in regards to the force they apply on the bones of hearing • Students would work to design a 3 D model of the middle ear and bones of hearing that could sense the amount of motion applied to them, specifically for work in stapedectomy and ossicular chain reconstruction (i. e. fixing broken hearing bones) • • • 2 Group Size: 2 -3 Skills: 3 D Modeling, Force Sensors, Materials Design Mentors: Pete Creighton, MD / Chris Razavi, MD / John Carey, MD – Francis.
